Answer:
The correct answer is -transfer fixed carbon dioxide to cells in which the Calvin cycle occurs
Explanation:
In C4 plants the light reaction and Calvin cycle occurs in two different cell that are mesophyll cell and bundle sheath cells. First, the CO₂ is fixed into 4- carbon oxaloacetate by an enzyme PEP carboxylase.
Then this oxaloacetate is converted into a simpler form called malate. Malate molecule then enters into bundle sheet cell and there it releases one molecule of CO₂. This CO₂ enters the Calvin cycle which results in the sugar formation with the help of enzyme rubisco.
Therefore by releasing of CO₂ molecule by malate in bundle sheet cells, it transfer fixed carbon for the Calvin cycle to occur.
Answer: The correct answer is-
Allopatric- option 2.
Sympatric - option 1.
Allopatric and sympatric are primarily the two major mechanisms for speciation ( formation of new species from an ancestral species).
In allopatric speciation, a population splits into two different species when it is isolated by physical or geographical barrier.
On the other hand, sympatric speciation occurs wihtin the same area. A population splits into two species that is becomes reproductively isolated when a change in the chromosome number occurs.
Thus, option first corresponds to sympatric whereas option second shows allopatric speciaton.

A single stranded DNA (oligonucleotides) can hybridize with (d) both complementary DNA and complementary RNA.
DNA is the Deoxyribonucleic Acid. It is the genetic material present in majority of organisms. The nitrogenous bases present in DNA are: Adenine, thymine, Guanine and Cytosine. DNA is a double stranded structure hence it forms hydrogen bonds with a complementary strand. The complementary strand can be of a DNA or RNA.
RNA is the Ribonucleic Acid. It also is a genetic material present in very few organisms. RNA is less stable than the DNA and may be either single stranded or double stranded. The nitrogenous bases of RNA are: Adenine Uracil, Guanine and Cytosine.
